Behind the heavy, soundproofed double doors of the estate’s private library, the air was thick with hostility. Chae-won stood near the grand mahogany desk, her arms crossed tightly over her chest, refusing to back down. Opposite her stood her older brother, Woo-jin, his expression dark and sharp as he paced the length of the room. Near the window, their sister, Ha-yun, watched the exchange with a cold, calculated stillness.

"You're being careless, Chae-won," Woo-jin said, his voice dropping to a harsh, dangerous whisper as he stopped pacing and glared at her. "Do you think we don't notice when you slip out past curfew? Do you think the Kims aren't monitoring the perimeter traffic?"

"I was at the studio working on the track demo, Woo-jin," Chae-won lied smoothly, her voice steady despite the adrenaline spiking in her veins. "If you checked the network logs like you always do, you'd see the server activity."

"Don't play dumb with me," Woo-jin snapped, stepping closer. "The Kims had a breach alert in their courtyard last night. They were waiting to catch whoever was foolish enough to step into that blind spot. And miraculously, the targets vanished right before the grid locked down. You expect me to believe you had nothing to do with that?"

Ha-yun finally spoke up from the shadows by the window, her tone deceptively calm but laced with venom. "If you are helping them, Chae-won, you are putting this entire family at risk. You know exactly what's at stake. If those girls dig up what happened seven years ago—if they find out the truth about J.Y. and Y.E.—the alliance won't just fall apart. It will destroy all of us."

Chae-won felt a chill run down her spine at the mention of those names, but she kept her face completely blank, channeling all her energy into a look of pure defiance.

"I don't care about your corporate alliances or your old secrets," Chae-won said coldly, looking both of her siblings dead in the eye. "I care about my music. If you want to waste your time chasing ghosts in the courtyard, go ahead. But keep me out of your paranoia."

Turning on her heel, Chae-won walked out of the library before either of them could stop her, slamming the heavy doors behind her. She needed to get back to her studio immediately—because if Woo-jin and Ha-yun were this close to figuring out she had warned the girls, the silent network Rora had built was the only protection they had left.

Meanwhile, back at the academy, So-min manages to slip into the media department's files during her free period.

Chapter 27: Clearing the Tracks

Inside the academy's crowded computer lab, So-min stared at the blinking cursor on the administrative monitor. She had successfully bypassed the basic directory filters, but when she searched the archive sheets for Hobi's primary contact data, the field was completely blank.

[SEARCH: HOBI // LOGISTICS_2019]
> RECORD NOT FOUND. 
> DATA SANITIZED BY SYSTEM ADMINISTRATOR.

Another dead end. Hobi’s digital history was as heavily guarded as the rest of the alliance's past.

Hearing the heavy footsteps of the lab supervisor approaching the door, So-min quickly tapped her auxiliary phone under the desk, sending a rapid, two-syllable distress signal through the encrypted childhood code.

Miles away, sitting in the back of her afternoon study hall, Rora saw the alert flash on her hidden screen. She didn't hesitate. Deploying a lightweight, remote clearing script she had pre-loaded into their local network, Rora remotely wiped So-min's session cache, scrubbed the temporary MAC address she had used to spoof the school terminal, and forced a clean system reboot on the lab computer.

By the time the teacher walked past So-min’s desk, the monitor was simply showing a standard, flickering school login page. So-min just sighed, stretched her arms, and grumbled out loud about the "terrible school Wi-Fi crashing again."

For the rest of the week, the trio went into absolute lock-down mode.

They walked the hallways with bright, careless smiles. They complained loudly about the upcoming math mid-terms, ate lunch in the crowded cafeteria, and didn't exchange a single serious glance. To the security cameras, to In-ah, and to the watchful eyes of the Kim family, they looked exactly like three ordinary teenagers who had been thoroughly spooked by a weekend scare and had happily retreated back into their safe, predictable lives.

They were ghosts in plain sight, perfectly waiting out the storm while the alliance families assumed they had won.

POV: The Control Room

Deep within the high-security wing of the Kim estate, the ambient light was cast entirely in shades of monitor-blue. Three figures stood before a massive, wall-mounted surveillance grid that displayed live, high-definition feeds from the academy corridors, the street corners, and the perimeter lines of the neighborhood.

Seo-jun, the eldest of the Kim siblings, stood with his hands resting on the back of a leather chair, his eyes fixed on the central screen. The camera showed Da-eun and Rora walking out of the school library, casually chatting about a textbook.

"They haven't made a single anomalous digital ping in seventy-two hours," Min-jun reported, his fingers tapping lazily on a control console as he pulled up the girls' cell tower metadata. "No burner activity detected on the local towers. No unauthorized encrypted handshakes. They’re just... going to class. Eating lunch. Going home."

Ji-hoon stepped forward, leaning against the console with a dark, dissatisfied scowl. "It’s too clean. They were at the perimeter wall. They received a warning from somewhere, and they vanished right before we closed the courtyard trap. You expect me to believe they just suddenly lost interest?"

"Fear is a powerful deterrent, Ji-hoon," Seo-jun said smoothly, his voice calm but layered with a cold authority. "They got a taste of what happens when they look too closely at the past. If they’re smart, they’re terrified. If they’re terrified, they blend in."

"And if they're acting?" Ji-hoon pressed, pointing at the screen where So-min was laughing at something on her tablet. "Look at them. It's a perfect rehearsal."

"Then we let them rehearse," Min-jun replied with a faint, cynical smile. "Every loop Rora deploys, every spoofed MAC address they try to use—I’ve got the filters set to log it silently. If they step out of line by even a millimeter, the system flags it instantly."

Seo-jun narrowed his eyes at the surveillance feed, watching the three girls leave the school grounds together, looking entirely ordinary.

"Keep the eyes on them," Seo-jun commanded quietly. "They think the danger was just in that courtyard. They have no idea how wide our net actually is. Let them play the part of innocent students for now. The moment they reach for the letters again... we close the loop for good."
